About a two weeks ago I was roughing out some wet bowl blanks and was really having issues with bogging down the motor. Using my 3/8" bowl gouge I was literally bringing the motor to a stop taking about a 1/4" cut. And no the belt was not just slipping. I opened the door to verify the motor pulley was actually coming to a stop. Fast forward to this past weekend and I'm back in the shop turning some stoppers and other smaller things. While sanding one of the stoppers at around 500 rmp I reached for the hand wheel to bring it to a quicker stop, and boy did it ever. The following is done at 3 times the stopper speed and with the belt on the high setting.

I'm looking for any input as to what may be causing this, motor, inverter, user lol. I should also mention that the front motor bearing has developed a slight clicking noise as of this weekend. According to Jet, the motor bearing is shot.
